(A) Fasting-induced BAT imaging with PLPEG-CNT. NIR Images of iBATs and aBATs with their arounds at post injection time of 1d. CNT accumulating area is brightly imaged. The brightness and contrast levels of all the images in (A) are the same. (B) Time course of PL intensities at iBAT for (PLPEG-CNT+, Fasting+) and (PLPEG-CNT+, Fasting−) conditions. The PL intensities denote the averaged intensities at the brightest area. The PL intensities at iBATs for “PLPEG-CNT−, Fasting− ” mice were about 1300 in (B). iBAT: interscapulum BAT, aBAT: axillary BAT (n = 4).
